DDR
This specification provides guidance on the performance of
3.3V devices in a 3.2 x 2.5mm package. Other supply voltage
options are available at 1.5V, 1.8V, 2.5V, 2.8V or 3.0V. Other
package size options are available as 2.0 x 1.6mm, 2.5 x
2.0mm, 5.0 x 3.2mm or 7.0 x 5.0mm.
Note: All Min and Max limits are specified over temperature
and rated operating voltage with 15pF output load unless
otherwise stated. Typical values are @ 25°C and nominal
supply voltage.

Programmable Drive Strength: The IQMS-134 includes a
programmable drive strength feature to provide a flexible tool
to optimise the clock rise/fall time for specific applications.
Slower rise and fall time provides reduced EMI. Fast rise and
fall time gives reduced jitter. Please contact an IQD Sales
Office to discuss options.

MEMS Oscillator Specification
IQMS-134
Output Control
Enable/Disable Mode (OE):
Logic ‘1’ (70%Vs min) to pad 1 enables the oscillator output.
Logic ‘0’ (30%Vs max) to pad 1 disables the oscillator output,
the output goes to a high impedance state. Only the output
driver is disabled. Supply current=4.2mA max. A pull-up
resistor of 10kΩ max is recommended if pad 1 is not externally
connected.
Output Enable/Disable Time (F=137MHz): 122ns max
(Note: For other frequencies time=100ns + 3 cycles.)
Standby Mode (ST):
Logic ‘1’ (70%Vs min) to pad 1 enables the oscillator output.
Logic ‘0’ (30%Vs max) to pad 1 the oscillator output is low level
(weak pull-down). Device goes to sleep mode. Supply current
reduces to 4.3μA max. A pull-up resistor of 10kΩ max is
recommended if pad 1 is not externally connected.
Resume Time (measured from the time pad 1 crosses 50%
threshold): 5ms max
No Connect Mode (NC):
No connection to pad 1 enables the oscillator output.
Input Pull-Up Impedance:
Pad 1: OE logic '1' or logic '0', or ST logic '1': 150kΩ max
Pad 1: ST logic '0': 2MΩ min
Start Up Time (measured from the time Vs reaches its rated
minimum value): 5ms max
Noise Parameters
Period Jitter (F=125MHz): 3ps RMS max
Phase Jitter (F=125MHz, 12kHz to 20MHz): 2ps RMS max
Peak to Peak Jitter (F=125MHz): 25ps max
Environmental Parameters
Storage Temperature Range: –65 to 150°C
Junction Temperature: 150°C max
Electrostatic Discharge: 2000V max
Mechanical Shock: MIL-STD-883F, Method 2002.
Vibration: MIL-STD-883F, Method 2007.
Thermal Cycling: JESD-22, Method A104.
Solderability: MIL-STD-883F, Method 2003.
